Cisco 300-620 Exam - Topic 9 Question 44 Discussion

Actual exam question for Cisco's 300-620 exam

Question #: 44
Topic #: 9

Refer to the exhibit.

A systems engineer is implementing the Cisco ACI fabric. However, the Server2 information is missing from the Leaf 101 endpoint table and the COOP database of the spine. The requirement is for the bridge domain configuration to enforce the ACI fabric to forward the unicast packets generated by Server1 destined to Server2. Which action must be taken to meet these requirements?

AEnable ARP Flooding

BSet L2 Unknown Unicast to Flood

CSet IP Data-Plane Learning to No

DEnable Unicast Routing

Show Suggested Answer

Suggested Answer: B

Both servers are in the same subnet. ARP flooding is out if we read the article in the link. Also unicast routing is not needed.

I’m not sure about that, but I guess it could work.

Setting L2 Unknown Unicast to Flood seems more effective.

Wait, is ARP Flooding really the best option here?

I think enabling unicast routing is important, but I’m not confident if that’s the right action for this specific situation.

I have a vague memory of IP data-plane learning settings, but I can't recall how they apply to this scenario.

This question feels similar to one we practiced where we had to decide on unicast flooding settings. I think option B might be the answer.

I remember studying about ARP flooding, but I'm not entirely sure if it's the right choice here.

I feel pretty good about this one. The conventional path load doesn't generate redo, and it only checks certain constraints, so I think I can narrow it down to the right answer.

I'm a little confused by this question. Is the Dev Hub the same as the Environment Hub? Or is it something different? I'll have to review my notes to make sure I understand the difference.

Hmm, I'm a bit unsure about this one. I'm trying to decide between B and D. I think visualizing the business vision through the lens of the business architecture could be really insightful, but establishing a target state solution architecture also seems important. I'll have to think this through a bit more.

This is a tricky one. I'll need to really understand the nuances of each quality function to pick the right answer. Time to review my study materials.
